ELMER E. RICE, OF EAU CLAIRE, WISCONSIN.

DETACHABLE HINGE.

No. 863,221. Specification of Application filed August-22,

To all whom it may concern:

Be it known that I, ELMER E. RICE, a citizen of the United States, residing at Eau Claire, in the county of Eau Claire and State of Wisconsin, have invented certain new and useful Improvements in Detachable Hinges, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in detachable hinges and consists in the novel construction, combination andarrangement of parts hereinafter described and claimed.

The object of the invention is to provide a simple, strong, durable and inexpensive hinge of this character for removably or detachably mounting screen doors, the covers or lids of sample cases, and similar swinging devices.

Further objects and advantages of the invention as well as the structural features by means of which they are attained, will be made clear by an examination of the specification, taken in connection with the accompanying drawings, in which the same reference numerals indicate corresponding portions throughout, and in which,

Figure 1 is a perspective view of my improved detachable hinge, looking at its inner side; Fig. 2 is a cross section taken on the plane indicated by the line 22 in Fig. 1; Fig. 3 is a view similar to Fig. 1 of a slightly modified form of the hinge; Fig. 4 is a cross section through Fig. 3 on the plane indicated by the line 4-4; Fig. 5 is an enlarged detail elevation of the rear or inner portion of the hinge shown in Fig. 1, showing a spring latch by means of which the tongues are prevented from becoming casually disengaged from their keeper openings; and Fig. 6 is a detail section taken on the plane indicated by the line 6-6 in Fig. 5.

Referring to the drawings by numerals, 1 and 3 denote the two members or leaves of the improved hinge, and 4 denotes a securing plate to which the member or leaf 3 is detachably connected. The hinge member or leaf 1 is adapted to be secured upon a door, a case or box cover or the like, by screws or similar fastenings inserted in openings 5 in said member. The securing plate 4 is adapted to be secured upon a door frame, a sample case or box or a similar structure, by screws or the like inserted in openings 6 formed in it. The detachable engagement or connection between the member 3 and the plate 4 is preferably effected byproviding on the member 3 a plurality of hook shaped tongues 7 adapted to enter keeper recesses or openings 8 formed in the plate 4. As shown, the tongues 7 are stamped out from the member 3 and are bent to project in opposite directions in the same horizontal or transverse plane. The keeper openings or slots 8 formed in the plate 4 have large upper portions 9 and small lower portions 10, opposite which latter upon the inner Letters Patent. 1906. Serial No. 831,644.

or under faces of the plate are formed recesses to receive said tongues and permit them to' lie within the plane of the inner face of said plate. The latter is of greater thickness than the member 3 so that the loops 7 lie entirely within the thickness of the plate 4 and engage the rectangular projections 11 formed by making the keeper openings as above described. This construction enables the plate 4 to be secured againsta flat door frame and renders it unnecessary to recess 01' cut out the-latter to permit of the insertion of the loops in the openings. I11 engaging the member 3 with the plate 4 the former is placed upon the outer face of the latter so that the tongues 7 enter the large upper portions 9 of the openings 8 and the member 3 is then dropped or moved downwardly so that the arms of the loops drop behind the projections 11 in the corners of said openings. In disconnecting the parts 3, 4 the above described operation is reversed. The hinge members 1. and 3 may be pivotally connected in any suitable manner, as shown, however, a pintle 12 is passed through alining tubular sockets 13 formed on the inner edges of said members.

The form of the invention shown in Figs. 3 and 4 is very similar to that of the one just described, the only difference being that the tongues 14 project inwardly toward each other and engage projections 15 which are similar to the projections 11 but which are arranged in the opposite corners of the keeper openings in the plate 4.

In order to retain the tongues on the member 3 in engagement with the projections on the plate 4, I may provide in one or more of the keeper openings 8 a spring latch such as the one shown in Figs. 5 and 6. This latch comprises a plate 16 of substantially rectangular form having its upper end bifurcated and formed with transversely alining apertures for the reception of the pivot pin 17. The latter is arranged in the plate 4 and extends across a recess 18 formed in said plate immediately above one of the openings 8. A spring 19 is coiled upon the pivot 17 in the bifurcated portion of the latch plate and has its opposite ends engaged with said latch plate and the bottom of the recess 18, so that it forces the latch plate in one direction and holds its lower end against one. of the projections 11 or 15. This lower end of the latch plate 16 is formed with a projecting finger piece 20 which works in a slot or recess 21 in'the plate 4. It will be seen that when the tongue 7 is inserted in the large portion 9 of the opening 8 in the plate 4, it will swing the latch inwardly and when said tongue is moved downwardly it will drop in rear of the projection 11 and when it drops beneath the plate 16 the spring 19 will force said plate inwardly so that its bottom edgelies above the tongue 7 and prevents it from moving upwardly in the opening 8. When it is desired to remove the tongue 7 from the opening 8, the finger piece 20 is engaged and the latch swung inwardly to permit the tongue 7 to pass upwardly between it and the projection 11, as will be readily understood upon reference to Fig. 5.

From the foregoing description, taken in connection with the accompanying drawing it is thought that the construction, use and advantages of the invention will be readily understood without a more extended explanation.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States is:

1. A detachable hinge comprising pivotally connected members, a securing plate and upper and lower pairs of ceive said tongues and permit them to lie within the thickness of said plate, substantially as shown and described.

2. A detachable hinge comprising pivotally connected members, a securing plate, an arm upon one of said members to engage a keeper upon said plate, a swinging latch pivoted upon said plate and adapted to engage said arm to hold it in engagement with said keeper and a spring for actuating said latch, substantially as shown and described.

3. A detachable hinge comprising pivotally connected members, a securing plate, an arm upon one of said members to enter a keeper recess or opening in said plate, a latch plate pivoted in said keeper recess or opening and adapted to retain said arm therein, a spring for actuating said latch plate and a finger piece projecting from said latch plate, substantially as shown and described.

In testimony whereof I hereunto aflix my signature in presence of two witnesses.

ELMER E. RICE.
